Deploy the ebpf-exporter helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `ebpf-exporter` Helm chart on the Linode Kubernetes Engine, you will need to follow a few steps with Pulumi. First, you need a Kubernetes cluster running on Linode. For simplicity, let's assume you have already provisioned a Linode Kubernetes Engine (LKE) cluster and have the kubeconfig available for Pulumi to use.

Now, let's deploy the `ebpf-exporter` Helm chart. To do this, you will use the `@pulumi/kubernetes` package, which allows you to manage Kubernetes resources using Pulumi.

Here's the high-level breakdown of what we'll do in our Pulumi program:

1. Import the necessary Pulumi and Kubernetes packages.
2. Create a Helm `Chart` resource that references the `ebpf-exporter` Helm chart.

Below is the TypeScript program which you will use to deploy the `ebpf-exporter` Helm chart onto your Linode Kubernetes cluster:

```typescript
import * as k8s from "@pulumi/kubernetes";

// Step 1: Provide the details about the Helm chart.
// This includes the name of the chart, the repository where the chart is located,
// and any specific configuration options you would like to set.
const chartName = "ebpf-exporter";
const chartVersion = "0.1.0"; // Modify with the correct chart version
const releaseName = "ebpf-exporter-release";
const namespace = "default"; // Specify the namespace where you want to install the chart

// You need to have Helm repo added with 'ebpf-exporter' chart or provide the exact URL for the chart
const helmChart = new k8s.helm.v3.Chart(releaseName, {
  chart: chartName,
  version: chartVersion,
  namespace: namespace,
  // Uncomment and specify below if you have a custom repo
  // fetchOpts: {
  //   repo: "https://helm-repo/ebpf-exporter",
  // },
  // Include values here if you need to customize the default configurations
  values: {
    // Custom values for 'ebpf-exporter' chart
    // ...
  },
}, { provider: k8sProvider });

// Optional step: Export the Helm release status
export const helmStatus = helmChart.status;

```

This program should be executed as part of a Pulumi project where you have already set up your Pulumi stack and Linode provider configuration. Ensure you install the necessary npm packages before running the program:

```bash
npm install @pulumi/pulumi @pulumi/kubernetes
```

When you run this program with `pulumi up`, Pulumi will deploy the `ebpf-exporter` Helm chart to your Linode Kubernetes Engine cluster. The program creates an instance of a `helm.v3.Chart` resource which Pulumi will manage like any other cloud resource. You can substitute the chart details and configuration options based on your exact requirements for the `ebpf-exporter` deployment.

Remember to configure Pulumi to use your kubeconfig file so that it can interact with your Linode Kubernetes cluster. This is often done through the Pulumi configuration system or by making sure that your kubeconfig is set up correctly in your environment.

After the deployment completes, you can use `kubectl get all -n default` or the namespace you specified to verify that the `ebpf-exporter` is running as expected. The export statement at the end is optional and can be used to export data about the Helm release from Pulumi's state.

If you need to make changes to the deployment, you can edit the Pulumi program and run `pulumi up` again to apply the changes. Pulumi will compute the difference and apply only the required changes.
